Building the record, in order
The goal is a file that a neutral reader could follow without having stood in the unit.
Pull the move-in record first
Find the move-in condition report and any photos from the start of the lease. An odor charge is far easier to explain when the file shows the unit was cleaned, painted or treated before this tenant arrived.
Walk the unit closed up
Enter after the house has been shut for several hours. Note in writing where the odor is strongest, what it smells like in plain words, and whether it changes with the furnace or AC running.
Photograph what odor leaves behind
Smoke film on light switch plates, yellowed blinds, tar streaks on window glass, stained ceiling texture around a light, residue on a wiped white cloth. These visible signs carry far more weight than a caption saying the room smells.
Date and label everything
Use file names or a log that ties each photo to a room and a time. A second person on the walkthrough who signs the notes adds credibility.
Get a written scope before work
Ask whoever performs the work to describe the source, the affected materials and the treatment. A scope written before cleaning shows the condition independently of the invoice.
Keep the invoice itemized
Separate odor work from routine turnover cleaning and from painting you would have done anyway. Lumped invoices make it hard to show what was caused by the tenancy.
Evidence that helps versus evidence that rarely does
| Item | Why it matters | Weakness to avoid |
|---|---|---|
| Move-in report noting a fresh, odor-free unit | Establishes the starting point | Vague phrases such as clean condition with no detail |
| Photos of visible residue | Shows a physical cause, not an opinion | Photos taken after cleaning has begun |
| Cloth wipe test photographed | Simple, repeatable proof of film on surfaces | No reference cloth from a clean area for comparison |
| Pre-work written scope | Independent description of the condition | Scope written after the fact to match an invoice |
| Itemized invoice | Ties a charge to a specific source | Single line item for whole-house cleanup |
| Lease clause on smoking or odor | Shows the tenant was on notice | Clause added at renewal without a signature |
Keep the tone factual
Describe what was found and what was done. Words like disgusting or destroyed make a statement look emotional, and an emotional statement invites a dispute. A line such as yellow residue on ceilings in living room and two bedrooms, cleaned and primed, is easier to defend than a paragraph of complaint.
Also separate normal aging from damage. Paint wears out on its own schedule, and a carpet near the end of its useful life does not become new because a tenant smoked on it. Many owners find it simpler to charge for the extra cleaning and treatment that residue required, and absorb the routine refresh they would have paid for anyway.
Common questions
Can a smell alone justify keeping part of a deposit?
That depends on the lease, the facts and current Colorado law, which is why an attorney should answer it. In practice, owners who pair odor notes with visible residue and a pre-work scope have a clearer record than those relying on a description of smell.
Should the tenant be invited to the move-out walkthrough?
Many landlords offer it. A joint walkthrough lets both sides see the same conditions, and notes signed by both reduce later disagreement.
